En-Bloc U-Shaped Osteotomy of the Mandible and Chin for the Correction of a Prominent Mandibular Angle With Long Chin.

J Craniofac Surg 2019 Jan 3. Epub 2019 Jan 3.

Department of Sixteen, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, Beijing, People's Republic of China.

Background: Lower face contouring surgery has become a popular aesthetic surgery in East Asian countries. Various surgical methods have been used to improve lower face aesthetics. When a patient has a wide as well as long lower face, procedures like chin polishing or T-type osteotomy are traditionally performed, but these surgical methods have several disadvantages. Read More

Denosumab-related osteonecrosis of the jaw: a report of 2 cases and review of the literature.

Gen Dent 2019 Jan-Feb;67(1):42-46

Bisphosphonates have been implicated in the induction of medication-related osteonecrosis of the jaw (MRONJ) since 2004. Since then, the spectrum of drugs implicated in the onset of MRONJ has broadened to include other antiresorptive and antiangiogenic drugs. Denosumab is an antiresorptive drug that has been on the market since 2010. Read More

[Current situation and future issues of antiresorptive agent-related osteonecrosis of the jaw].

Nihon Yakurigaku Zasshi 2019 ;153(1):22-27

Department of Dentistry and Oral Surgery, Hyogo College of Medicine.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ), which is characterized by refractory bone exposure, has recently emerged as a serious side effect of bisphosphonate (BP) treatment. BRONJ was first thought to be due to administration of high doses of intravenous BP to treat metastatic bone lesions or multiple myeloma. However, more recent studies have indicated that BRONJ also frequently occurs in patients receiving low doses of BP for the treatment of osteoporosis. Read More

Is the conservative non-surgical management of medication-related osteonecrosis of the jaw an appropriate treatment option for early stages? A long-term single-center cohort study.

J Craniomaxillofac Surg 2018 Dec 29. Epub 2018 Dec 29.

University of Heidelberg, Department of Oral and Maxillofacial Surgery, (Head of Department: Prof. Dr. Dr. J. Hoffmann), Im Neuenheimer Feld 400, D-69120, Heidelberg, Germany.

Plasminogen Activator Inhibitor-1 4G/5G Polymorphism Contributes to Osteonecrosis of the Femoral Head Susceptibility: Evidence from a Systematic Review and Meta-analysis.

Arch Bone Jt Surg 2018 Nov;6(6):468-477

Research performed at the Department of Orthopedics, Shahid Sadoughi University of Medical Sciences, Yazd, Iran.

Background: The Plasminogen Activator Inhibitor-1 gene 4G/5G (PAI-1 4G/5G) polymorphism has been suggested to be associated with osteonecrosis of the femoral head (ONFH) susceptibility; however, the results are conflicting and inconclusive. We have carried out a comprehensive meta-analysis to derive a more precise estimation of the association.

Methods: A comprehensive search in PubMed, EMBASE, Google Scholar, and ISI Web of Knowledge databases was conducted to identify all eligible case-control publications investigating the association between PAI-1 4G/5G polymorphism and ONFH risk. Read More

A real-world study assessing the use of bone-targeted agents and their impact on bone metastases in patients with prostate cancer treated in clinical practice in Europe.

J Bone Oncol 2019 Feb 18;14:100212. Epub 2018 Dec 18.

Amgen Inc., Thousand Oaks, CA, USA.

Background: Bone metastases (BMs) are common in patients with prostate cancer and can lead to skeletal-related events (SREs), which are associated with increased pain and reduced quality of life (QoL). Bone-targeted agents (BTAs), such as zoledronic acid and denosumab, reduce the incidence of SREs and delay progression of bone pain.

Methods: We evaluated the management of BMs and pain in six European countries (Belgium, France, Germany, Italy, Spain and the UK) using the Adelphi Prostate Cancer Disease Specific Programme. Read More

Department of Oral and Maxillofacial Surgery, The Affiliated Stomatological Hospital of Nanjing Medical University, Nanjing, China.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a detrimental side effect of the long-term administration of bisphosphonates. Although macrophages were reported to be an important mediator of BRONJ, the detailed potential mechanism of BRONJ remains unclear. Here, we reported an elevated TLR-4 expression in macrophages under action of zoledronic acid (ZA), resulting in enhanced M1 macrophage polarization and decreased M2 macrophage polarization both in vitro and in vivo.

In dysplastic infant hips undergoing abduction harness treatment, cartilage contact pressure is believed to have a role in therapeutic cartilage remodeling and also in the complication of femoral head avascular necrosis. To improve our understanding of the role of contact pressure in the remodeling and the complication, we modeled cartilage contact pressure in cartilaginous infant hips undergoing Pavlik harness treatment. In subject-specific finite element modeling, we simulated contact pressure of normal and dysplastic hips in Pavlik harness at 90° flexion and gravity-induced abduction angles of 40°, 60° and 80°.

Segmentation of the proximal femur in radial MR scans using a random forest classifier and deformable model registration.

Int J Comput Assist Radiol Surg 2019 Jan 2. Epub 2019 Jan 2.

School of Health Sciences - Geneva, HES-SO University of Applied Sciences and Arts Western Switzerland, Avenue de Champel 47, 1206, Geneva, Switzerland.

Background: Radial 2D MRI scans of the hip are routinely used for the diagnosis of the cam type of femoroacetabular impingement (FAI) and of avascular necrosis (AVN) of the femoral head, both considered causes of hip joint osteoarthritis in young and active patients. A method for automated and accurate segmentation of the proximal femur from radial MRI scans could be very useful in both clinical routine and biomechanical studies. However, to our knowledge, no such method has been published before. Read More

Grafting, Stripping and Stapling of Helical Peptides from the Dimerization Interface of ONFH-Related Bone Morphogenetic Protein-2.

Protein J 2019 Jan 2. Epub 2019 Jan 2.

Department of Orthopedics, The Second Affiliated Hospital of Xi'an Jiao Tong University, Xi'an, 710004, China.

Transforming growth factor-β/bone morphogenetic protein (TGF-β/BMP) signaling plays a fundamental role in embryonic skeletal development and postnatal bone homeostasis. The signaling pivot protein BMP-2 belongs to the TGF-β superfamily and has been implicated in the pathogenesis of osteonecrosis of femoral head (ONFH). The biologically functional BMP-2 is a homodimer that has two tightly packed cores at its dimerization interface; each core is defined by the intermolecular interaction between a helical arm from one monomer and a hydrophobic pocket from another monomer.

Lateral rim mesh in primary total hip arthroplasty.

Bone Joint J 2019 Jan;101-B(1):96-103

Department of Orthopaedics, Radboud University Medical Center, Nijmegen, The Netherlands.

Aims: The aim of this study was to analyze the effect of a lateral rim mesh on the survival of primary total hip arthroplasty (THA) in young patients, aged 50 years or younger.

Patients And Methods: We compared a study group of 235 patients (257 hips) who received a primary THA with the use of impaction bone grafting (IBG) with an additional lateral rim mesh with a group of 306 patients (343 hips) who received IBG in the absence of a lateral rim mesh during the same period from 1988 to 2015. In the mesh group, there were 74 male and 183 female patients, with a mean age of 35 years (13 to 50). Read More

Benefits and risks of adjuvant treatment with zoledronic acid in stage II/III breast cancer. 10 years follow-up of the AZURE randomized clinical trial (BIG 01/04).

J Bone Oncol 2018 Nov 27;13:123-135. Epub 2018 Sep 27.

Edinburgh Cancer Research Centre, Western General Hospital, University of Edinburgh, UK.

Adjuvant bisphosphonates improve disease outcomes in postmenopausal early breast cancer (EBC) but the long-term effects are poorly described. The AZURE trial (ISRCTN79831382) was designed to determine whether adjuvant zoledronic acid (ZOL) improves disease outcomes in EBC. Previous analyses showed no effect on overall outcomes but identified benefits in postmenopausal women. Read More

Avascular necrosis of the femoral head: An exceptional complication of cushing's disease.

Ann Afr Med 2018 Oct-Dec;17(4):225-227

Department of Endocrinology and Diabetology, University Hospital of Fez, Fez, Morocco.

Avascular necrosis (AVN) of the femoral head is a well-recognized complication of steroid treatment. Exogenous glucocorticoids' administration and alcoholism are the most common nontraumatic etiologies. AVN secondary to endogenous hypercortisolism (HC) is rare; very few case reports are available on this complication. Read More
